i e eH -tezze To-rill whom-'51, maytoncerhn r i 3 EBe it known that 1 GHARLES] E. GERvAIs, a citizen of the "United States residing .at Jacksonville, inthe county of lDuval, i$tate of Florida, have invented certain new -and useful Improvements in "Douche-Nozzles; and I do -hereby declare the following :to be aifull, 'clear andtexact "description of'the invention, such as will enable others :skilled inthe-artto:whieh it appertainsto make and use'the same] This invention relatesto douche nozzles and more particularly -to such nozzles designed especially for yaginal 'irrigations, and has for its obj ect to provide a deuche nozzle which willconform to the vaginal anatomy with :resp ect especially to the cervix uteri ,and the portion of the vaginal passage lying directly thereabove. it is well known that "this particular portion of the vagina .is most 'difliculfiof access with the usual type of douche nozzle;- since it is pracmany out off by the cervix, and the "insertion of the ordinary douche nozzle has a v tendency to force the cervix upwardly, resulting ina fold oftissue-at the un'ionrof the cervix withthe vaginal wall directly above the cervix whichfoldhasa tendencyito retain and propagate. any pathogenic organisms which be present. Itisaprimary purpose of the present invention to produce a nozzle which will thoroughly irrigate all portions of the yagina while permitting the cervix to remain in itsfnorm al position.

It is also well known that-in many cases the vaginal wall will form in folds at other points, and 'it is obvious that wherever such a fold occurs the difiiculty of properly irrigating the tissue is materially increased. It is an object of the present invention to provide a nozzle so constructed that it may be manipulated in a way to eliminate such folds thus making possible the thorough irrigation of the entire vaginal surface.

Another object is to provide a structure in which that portion of the nozzle which enters above the cervix will be so constructed as to cause a spreading of the irrigating fluid in the form of a rosette or circular spray.

At its end portion opposite ;to :the enlarge- 1nent 6 :the tubej5 is provided .withaq lurality of spaced lateral openings 5 -10 -which communicate ..with the passage 9 and, as illustrated, the :passage 1,9 opens through the end of the tube which is distant from the enlargement .6. i

The major portion .of the tube 5 is. surrounded by a .-cage .11 1 which includes an .annular member .12 iinteriorly :threaded has shown at 18 for engagement withithe threads of the (portionz8, so as to rest with its face ll-Zagainst the flange Z. ,TlllSufttCB 14 is fiat but the opposite face :15 is curved from the periphery ofthe central opening oftheinembBI'dZOlthG periphery, offtthe Eface 14 so that the member has approximately the shape of A-plurality of equidistant openings 16 are formed through the member 12 from the face 14 to the face 15, these openings surrounding the central opening 13 in a circular series.

Secured to the face 15 of the member 12 there are a plurality of longitudinally extending rods 17, one rod being located between each pair of openings and these rods project at their opposite ends beyond the free end of the tube 5 where they are turned inwardly as indicated at 18 and are secured to a conical member 19 adjacent to the base of this member, the member 19 lying with its apex directed toward the free end of the tube 5 and directly opposite the open end ofthepassage thereof. As shown in fluid. It will thus be seen that the spacing the drawingthe. conical member- 19. .is spaced.

from the end of the tube 5. ,7 llhe several rods 17 are spaced considerable from each other as illustrated and the of the. rods to a relatively great extent is important and that it is also important that this rod structure be employed to prevent abrasion of the tender and'sensitive" tissues spaces between the rods are considerably greater than the diameters of the rods.

Between their ends but at a point nearer the conical member 19 than the member 15 i the 'ca'ge'llis circumferentially constricted, this being produced by eurvingthe rods of this point inwardly toward the tube 5.

:Inuse the cage'llfis inserted within the vaginal passage, the end of the. cage adjacent to the member 19-.being passed beyond the cervix and the member 15 being .disposed'in contact with the labiav minora or with the walls of the vagina. directly thereabove. It will be understood that, though the cervix may be lifted by, the engagement of the free end of the cage therewith, it will bevpermitted to return to its normal position when the outer end of. the constricted portion of the cage has passed thB'ZCGIVlX. 25

When the irrigating fluid is permitted .to pass through the tube 5. it will find egress through theopenings 10 to the surface. of the cervix and by reason of the fact that the I cage holds the vagina slightly distended, the

fluid, will have free passage down to the openings 16 and out therethrough.

The irrigating fluid will also find egress through the open end of the passage 9 and,

striking thesurface of the cone member 19 will be deflected in the form of a rosette or circular spray to thoroughly irrigate the tissue surfaces above the cervix.

During the process of irrigation a rotary i3 motion imparted to the nozzle will result i Copies of this patent may beobtained for in movement of the rods 17 over themucous membrane of the vagina, thus eliminating any folds therein and exposing all portions thereof to the action of the fluid. By reason of the fact that the rods 17 are consid- 'erably spaced from each other the tissue may extend between these rods and thus receive the full action of the lrrigating during the rotary movement of the nozzle.

By reason of the fact that the tube 5 has threaded connection with the ca e, the rod may be turned with respect to tie member 15 which will result in movement of the free end of the tube toward or away from the cone member 19 and this will cause a variation in theforce, of the circular spray as .well as in its volume. Thus, after the nozzle. has been inserted the tube may be manipulated to vary the circular spray to produce the best result.

l/Vhat I claim is A douche nozzle consisting of a base member having a tube-attachin stem and a radiating flange beyond which it is exteriorly threaded, an annular member screwed onto the threaded portion and having perforations therethrough ranging longitudinally of the base member, a cone having rods radiating from its base and ranging with compound curves past the'apex of the cone with thechords of their curvatures parallel with the extension of the axis of the cone past its apex, the ends of the rods being engaged in lternate perforations of the annular member and a tube carried by the base member and forming a continuation of the bore thereof, the tube extending with its axis coincident with the extension of the axis of the cone beyond its'apex, equidistant from and in spaced relationto the rods, the tube having its end opposite to the base in close proximity to the cone to discharge against the wall thereof and having radial perforations in its free end portion.

In testimony whereof, I afiix my signature, in the presence of two witnesses.
